The purposes of this study were to find the general trends and differences factors influencing single mothers' psychological well-being, and, analyze the effects of family, and social variables on their psychological well-being. The subjects were the 284 single mothers living in Kwangju and Chonnam. The data were analyzed with frequency, t, F, and Pearson's r test, and by multiple regression using SPSS. The major findings were as follows: 1. Single mothers' family variables were lower than the median, but instrumental support was higher than emotional support. Single mothers' psychological well-being was found to be around that of the median value. 2. Single mothers' psychological well-being was significantly different from family stress, family resources, mother-child conflicts, income, emotional support, participation of education program, and institutional support. 3. Life satisfaction of single mothers was influenced by institutional support, family stress, family resources, and emotional support. Depression among single mothers was influenced by family stress, family resources, mother-child conflicts, and institutional and emotional support.

Purpose: The purpose of this study was to identify the impact of activities of daily living, instrumental activities of daily living and depression on life satisfaction among aged women. Methods: The sample consisted of 309 aged women of over 60. Data were analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression analysis. Results: Significant factors affecting the life satisfaction were spouse, religion, perceived health status, age, and depression. The most significant variables among them were depression and perceived health status. The explanatory power on life satisfaction was 57% in regression model. Conclusion: Depression and perceived health status are important variables to influence on life satisfaction. Therefore, it is suggested that nursing intervention to reduce or prevent depression and enhance health status should be developed to promote quality of life in aged women.

This study investigated the correlation between learners' psychological and social factors and their syntactic complexity of speaking. The study collected samples of Korean spoken production of 61 learners with English, Chinese, Japanese and other L1 backgrounds and applied mini-TOPIK, mini-AMTB, and SASIQ for 70 minutes. The study found that: (i) integrative motivation showed positive correlation with a number of simple complex clauses, but instrumental motivation correlated negatively with a number of adverbial clauses, indicating that high motivation hindered producing highly complex clauses although it triggered producing simple complex clauses, (ii) social contact with L2 native speakers showed positive correlation with general L2 development and a number of simple complex clauses, but revealed negative correlation with double or triple complex clauses, (iii) hours of L2 listening showed very strong positive correlation with producing triple complex clauses and general proficiency, but indicated negative correlation with a number of simple complex clauses. The study reported that high motivation toward Korean learning and active social activities with Korean native speakers helped produce simple complex clauses while hours of listening to Korean helped produce triple complex clauses.

This study examined factors related to the motivation for the uses of cellular phones and the relationship between motivation for cellular phone use and parent-child communication among middle school students. A total of 223 questionnaires were submitted and analyzed. The characteristics of motive structure of the middle school students were found as recreation, time management, information-seeking, reassurance and fashion/showing off. Among those motivations, these middle school students examined here were found to use cellular phones in similar ways to how conventional telephone is used such as work/instrumental reasons and socializing/entertaining. The motivations showed a significant association with the level of parent-child communication. Information-seeking and time management motivation were positively related with an open communication level while fashion/showing off and recreation were negatively related with an open communication level.

Purpose: This study examined the health status of elderly. Method: This is a survey using cross-sectional design. The subject were 122 elders who were 65 and over in Daejeon. Instrumental activity of daily living, nutrition and Body mass index for physical health status, social engagement for social health status, and depression and loneliness for emotional health status were measured. Results: Independent level was medium, and nutrition and BMI were normal level. Social engagement score was 2.38 which means low. Mean depression level was 7.71 and mean loneliness level was 56.77, which means high. The risk factors for vulnerable health status were no spouse, lower pocket money, living at institution, poor subjective health status. Conclusion: This finding indicates that the elderly subjects were in normal physical health status, but social and emotional health status were poor.

The deterioration of concrete due to sulfate ions in various sulfate environments such as groundwater, soil and seawater is one of important factors degrading the durability of concrete structure. The aim of this paper is to evaluate on the magnesium sulfate alttack resistance of mortars with silica fume. In this study, compressive strength loss and length change of prismatic mortars, containing silica fume, immersed in 5% magnesium sulfate solution for 270 days were investigated. Additionally, paste powders with same binder were used to observe reactants of cement matrices through the instrumental analysis such as XRD, SEM and MIP. Results obtained from this study indicate that the greater damaging effects of the magnesium soulution are due to the decomposition of the C-S-H gel to M-C-S-H.

Recently, there has been a intensive social interest for concrete structures with respect to durability by carbonation, chemical attack etc. Specially, the deterioration of concrete due to chemical attack in environments such as Wastewater Treatment Facilities is important factors degrading the durability of concrete structure. The purpose of this paper is to evaluate on deterioration of Wastewater Treatment Facilities concrete to chemical attack through instrumental analysis such as XRD, SEM and EDS. According to the results of this study. Wastewater Treatment Facilities concrete to chemical attack due to $So_{4}^{2-},\;Mg^{2+}$ ions founded out to appear deterioration materials peak : ettringite/thaumasite. gypsum and brucite peak.

This qualitative study focused on the motives and patterns of child care leave by analyzing its facilitating and constraining factors. Fourteen participants were interviewed in-depth using non-structured interview questions. Motives for child care leave include mothers' active choice, mothers' inevitable secondary choice, and mothers' instrumental choice. The patterns of child care leave in terms of total period, time, and distribution vary according to individual circumstances and occupational culture surrounding child care leave for female workers. Female workers will occasionally use this child care leave as a rare opportunity to take a rest during their labor lifecycle and to achieve work-family balance.

During last years, large investments have been directed to development and research of nano-technological products like semiconductor, display panel, optic-fiber communication components, life technology, and ultra-precision components. All quantitative measurements at nanometre scale should guarantees accurate results and high quality. Laser interferometer is one of most famous nanometre scale devices to be able to measure metre-scale distance with nanometre scale resolution, but it is easily affected by various error causes like geometrical, instrumental and environmental factor. On the other side, capacitive sensor is robust to above error factors, but it is able to measure relatively shorter distance, under $100{\mu}m$, than laser interferometer. New error correction method for laser interferometry using capacitive sensor will be introduced in this paper.
